Lear you're confusing business model and industry model. Free enterprise is a good thing, this industry model is what's the problem, it's not truly free. It's being manipulated by marketeers, GE capital and such.
Imagine if the ice cream stores in your town had a very hi capital cost requiring financing to sell, these folks would be be holding to the likes of GE. Imagine price wars resulting in just one bankruptcy, but GE doesn't want their capital ice cream machine idled, so they make a deal to undercut this competitors costs (pay to keep the engines running), and that competitor now undercharges for its product, then others fail and so on. That in essence is what's happening in our industry.
Imagine if when a bankruptcy occurred, that business was truly liquidated or set back on its feet with true costs, not illusory lower costs because someone outside the business favored that business for their gains. Imagine if a bankruptcy actually required you to repay your debts. Imagine if a company once through bankruptcy was forbidden from trying it a second or third or as what's happened, a way of business, bankruptcy to control costs.
That is the problem, not the free market.
Taking it a step further, if regulation did return, how much air service would be eliminated? I wager well over 50%. Why, because if you have a monopoly, and can pretty much charge what you want, if you do, you lose share, so instead, you reduce capacity to the point which a comfortable profit margin exists.
Pre deregulation only fifteen percent of the US population had flown a plane, that figure is now 85%. Somewhere between those two numbers 15 and 85 is where a regulated industry would thrive and be controlled. Now, are you in favor of losing half our jobs so companies have a monopoly?
